Refill Gaps Don't Prove Recovery: A Clinical Pearl for PI Attorneys

Amar Lunagaria — Co-Founder & Chief Pharmacist, LienScripts | March 4, 2026 | 9 min read

Defense counsel routinely points to gaps in prescription refill records as evidence that the plaintiff recovered. In clinical reality, refill gaps are caused by insurance barriers, prescriber transitions, medication shortages, and other non-recovery factors. Learn how to rebut this common defense tactic with pharmacy evidence.

A gap in a plaintiff's prescription refill history does not prove recovery -- and any defense attorney who argues otherwise is misrepresenting how pharmacy systems and patient care actually work. Refill gaps are among the most commonly mischaracterized evidence in personal injury litigation, and plaintiff attorneys who understand the clinical reality behind these gaps can dismantle this defense tactic before it gains traction.

• Refill gaps occur for numerous non-recovery reasons: insurance authorization delays, prescriber transitions, pharmacy transfers, drug shortages, hospitalization, and financial barriers
• Defense counsel routinely mischaracterizes refill gaps as evidence that pain resolved or treatment was no longer needed
• LienScripts tracks every dispense and generates a MERIT (Medication Evaluation & Rationale for Injury Treatment) report that documents the clinical context surrounding refill gaps
• A refill gap followed by resumed filling is actually stronger evidence of ongoing need -- the plaintiff attempted to go without the medication and could not
• Proactive explanation of refill gaps in demand packages prevents defense counsel from using them as false recovery evidence

Why Refill Gaps Happen

Insurance Authorization Barriers

Prior authorization requirements are one of the most common causes of refill gaps. When a prescription requires insurance approval, the process can take days or weeks. During that gap, the patient has no medication -- not because they do not need it, but because the payer has erected an administrative barrier. The insurance denial or delay is documented in pharmacy system records, and LienScripts captures these events when they occur within its dispensing network.

Step therapy requirements create similar gaps. An insurer may require the patient to try a cheaper medication before approving the prescribed one. The patient may go without the preferred medication during this forced trial period, creating a gap that has nothing to do with clinical improvement.

Prescriber Transitions

Personal injury patients frequently transition between prescribers -- from the emergency department to a primary care physician, from primary care to a specialist, from one specialist to another. Each transition requires a new prescriber to evaluate the patient and write new prescriptions. The gap between the last fill from the prior prescriber and the first fill from the new prescriber is a transition gap, not a recovery gap.

As Amar Lunagaria, PharmD, LienScripts' Chief Pharmacist explains, "I review cases regularly where a two-week refill gap coincides exactly with a prescriber transition. The patient ran out of medication under Prescriber A, could not get a refill without a new prescription, waited for their appointment with Prescriber B, and then resumed filling the same medication at the same dose. That gap tells me the patient was without medication against their will -- not that they recovered."

Pharmacy Transfers

When a patient changes pharmacies -- whether because of a move, insurance network changes, or personal preference -- the transfer process can create a gap. Prescription transfers require communication between pharmacies, verification of remaining refills, and sometimes a new prescription from the prescriber. The administrative delay during transfer is unrelated to clinical status.

Drug Shortages

National drug shortages affect hundreds of medications at any given time. The FDA's drug shortage database documents these shortages publicly. When a plaintiff's medication is on national shortage, the pharmacy may be unable to fill the prescription regardless of clinical need. This is an external supply chain issue, not a clinical event.

Financial Barriers

Patients on liens or without insurance coverage may face periods where they cannot afford their medications. A plaintiff who skips a refill because they cannot pay the cash price has not recovered -- they have been denied treatment by financial circumstances that the defendant's negligence created. This is particularly relevant in cases where LienScripts' lien-based dispensing was not yet in place during the gap period.

Hospitalization or Competing Treatment

A plaintiff who is hospitalized receives medications through the hospital pharmacy, which does not appear in the outpatient pharmacy record. A hospitalization gap is actually evidence of worsening, not recovery. Similarly, a plaintiff who undergoes a procedure or surgery may temporarily discontinue certain medications per surgical protocol, creating a perioperative gap.

The Gap-and-Resume Pattern: Stronger Than Continuous Fills

Here is the clinical pearl that defense counsel does not want juries to understand: a refill gap followed by resumed filling is actually more powerful evidence of ongoing need than uninterrupted refills.

When a plaintiff stops filling a medication -- for any reason -- and then resumes filling the same medication at the same or higher dose, the resumption demonstrates that:

1. The plaintiff tried to go without the medication. Whether the gap was voluntary or involuntary, the plaintiff experienced a period without pharmacological management.
2. Symptoms returned or persisted without medication. The plaintiff resumed filling because they needed the medication. The gap period proved that the underlying condition had not resolved.
3. The prescriber re-authorized the medication. After the gap, the prescriber evaluated the patient and determined the medication was still needed, issuing a new prescription or authorizing a refill.

This pattern -- stop, suffer, resume -- is documented in the pharmacy record as a medication discontinuation and rechallenge event. It is one of the most powerful evidence patterns available to plaintiff attorneys.

How to Proactively Address Refill Gaps

In the Demand Package

Do not wait for defense counsel to raise refill gaps. Address them proactively:

1. Identify every gap in the refill chronology (any interval longer than the expected refill date plus 7 days)
2. Investigate the cause of each gap: prescriber transition, insurance barrier, pharmacy transfer, shortage, or other documented reason
3. Explain the gap in the demand narrative with the specific cause and supporting documentation
4. Emphasize the resumption -- the fact that filling resumed proves the gap was not due to recovery

The MERIT report from LienScripts includes gap analysis when gaps are present in the dispensing record. The pharmacist-authored narrative explains the clinical context, preventing defense counsel from mischaracterizing administrative or logistical gaps as clinical improvement.

At Deposition

Prepare your client to explain any refill gaps before defense counsel asks. A plaintiff who can articulate, "I ran out of refills when I switched from Dr. Smith to Dr. Jones, and I went two weeks without my gabapentin, which was miserable -- the nerve pain came back worse than ever" preempts the defense narrative and turns the gap into evidence of ongoing severity.

With Pharmacy Records

Request documentation of insurance denials, prior authorization delays, and pharmacy transfer records. These administrative records provide objective, third-party documentation that the gap was caused by a system barrier, not by clinical improvement.

Common Defense Gap Arguments and Rebuttals

"The plaintiff went three weeks without medication, proving pain resolved."

Rebuttal: The gap coincided with a prescriber transition (documented by appointment records). The plaintiff resumed the same medication at the same dose immediately after the new prescriber's first visit. The gap proves the plaintiff needed a new prescription, not that they stopped needing medication.

"If the medication were truly necessary, the plaintiff would have found a way to fill it."

Rebuttal: This argument blames the plaintiff for systemic barriers. Insurance authorization delays, pharmacy transfer timelines, and prescriber scheduling constraints are outside the patient's control. The plaintiff's inability to obtain medication during these administrative gaps is not evidence of recovery -- it is evidence of the barriers injured patients face.

"The gap occurred during the same period the plaintiff claims to have been in severe pain."

Rebuttal: The gap is consistent with severe pain. The plaintiff was without medication during this period, meaning their pain was unmanaged. The gap did not relieve pain -- it removed the treatment that was managing pain, likely making the plaintiff's experience worse.

LienScripts generates a MERIT (Medication Evaluation & Rationale for Injury Treatment) report for every case, providing pharmacist-signed documentation for demand packages that includes contextual analysis of refill gaps and their clinical significance.
